7s_prompts prompt: I'm gonna regret this, aren't I?

(OOC: Okay so... Ollie!Mun challenged me to write this. This is canon for all my current Chloes, except Quiver verse. This is, in my head, how Chloe's first time happened when she was sixteen, with Jimmy Olsen and it's completely from her point-of-view. Feedback is greatly appreciated.)

( This is more like a very strong PG-13, but I will say R just to be safe. )
